Fluid Bed Dryer

Fluid Bed Dryer offers a lucid solution to drying of wet granules. It utilizes the principle of passing the hot air at a high velocity through the bed of the material to be dried, causing it to float on a cushion of air.

The process air is supplied to the bed through a special perforated distributor plate and flows through the bed of solids at a velocity sufficient to support the weight of particles in a fluidized state.

Bubbles form and collapse within the fluidized bed of material, promoting intense particle movement. In this state, the solids behave like a free flowing boiling liquid.   Very high heat and mass transfer values are obtained as a result of the intimate contact with the solids and the differential velocities between individual particles and the fluidized gas.
